    completion, it normally explains what's wrong and how to fix it.
    If you can't work it out, or if it's being uncommunicative, post 
    the errors in the 
    <A

    <A

    <A
HREF="configuration.html"
>Section 2.2</A
> (Configuration) but accessing the Bugzilla
    URL doesn't work, the first thing to do is to check your web server error
    log. For Apache, this is often located at
    <TT
CLASS="filename"
>/etc/logs/httpd/error_log</TT
>. The error messages
    you see may be self-explanatory enough to enable you to diagnose and
    fix the problem. If not, see below for some commonly-encountered 
    errors. If that doesn't help, post the errors to the newsgroup.

>&#13;      Bugzilla can also log all user-based errors (and many code-based errors)
      that occur, without polluting the web server's error log.  To enable
      Bugzilla error logging, create a file that Bugzilla can write to, named
      <TT
CLASS="filename"
>errorlog</TT
>, in the Bugzilla <TT
CLASS="filename"
>data</TT
>
      directory.  Errors will be logged as they occur, and will include the type
      of the error, the IP address and username (if available) of the user who
      triggered the error, and the values of all environment variables; if a
      form was being submitted, the data in the form will also be included.
      To disable error logging, delete or rename the
      <TT
CLASS="filename"
>errorlog</TT
> file.
